Different cookie handlers for two chromium instances on one form

问题

I'm using DCEF3 on Delphi XE3.

Task is : Create different cookie storages for different TChromium instances.
Problem : I'm creating different ICefCookieManager instances for each TChromium instances and its returning in GetCookieManager event.

Example code:

type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Chromium1: TChromium;
    Chromium2: TChromium;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure Chromium1GetCookieManager(Sender: TObject;
      const browser: ICefBrowser; const mainUrl: ustring;
      out Result: ICefCookieManager);
    procedure Chromium2GetCookieManager(Sender: TObject;
      const browser: ICefBrowser; const mainUrl: ustring;
      out Result: ICefCookieManager);
  private
    { Private declarations }
      CookieManager: ICefCookieManager;
      CookieManager2: ICefCookieManager;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

procedure TForm1.FormCreate(Sender: TObject);
begin
    CookieManager:=TCefCookieManagerRef.New('C:\Cookies\1');
    CookieManager2:=TCefCookieManagerRef.New('C:\Cookies\2');
end;

procedure TForm1.Chromium1GetCookieManager(Sender: TObject;
  const browser: ICefBrowser; const mainUrl: ustring;
  out Result: ICefCookieManager);
begin
    Result:=CookieManager;
end;

procedure TForm1.Chromium2GetCookieManager(Sender: TObject;
  const browser: ICefBrowser; const mainUrl: ustring;
  out Result: ICefCookieManager);
begin
    Result:=CookieManager2;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
    Chromium1.Load('http://somesite.com');
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
    Chromium2.Load('http://somesite.com');
end;

If I add ShowMessage('First') to Chromium1GetCookieManager event, and ShowMessage('Second') to Chromium2GetCookieManager, always the message "First" will be shown, no matter whether I press button1 or button2.
In other words Chromium1GetCookieManager is called for both instances.

Problem is solved, thanks to all.

How to solve the problem?
Just turn off cefsingleprocess variable in your project1.dpr.
Example:

program Project1;

uses
  Forms,
  cefvcl,
  ceflib,
  Unit1 in 'Unit1.pas' {Form1};

{$R *.res}

begin
  CefSingleProcess := False;//this what i'm talking about
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.
